[TenTec] Ten Tec Orion II problem -- will not power on

[Rod Greene]

 Be very suspicious of the power connector at the back of the Orion. I had to change mine for power poles. The connectors are well known for causing problems like this.

 Thanks Bernard.  I already have.  I checked on 2 other power supplies with the same result.  The LCR also indicates that the repairs I made on the A9 board are still sound.  While I have checked continuity on the power connector, I'll give it another look and make sure it has a GOOD connection.  However, with the observed amperage draw I suspect that the power connector is fine.

I would try another power supply and check the A9 board (it may have failed after you rebuilt it).

I would also check the integrity of the power connector.

While I thank Mike for taking care of this, and rejecting offers he received to buy the lot, I do have a complaint.  My rig has come back to me in non-functioning condition.

The rig immediately draws around 6 amps and drops the voltage on an Astron RS-35M to about 5 volts.  Obviously I don't leave it in this condition, but the rig is now useless to me until I can figure out how to fix it and where to start.
